Model MGP-EW301V Bipolar Detection Variable High-sensitivity Electromagnetic Sensor


  • Magnet detection


  • The sensitivity can be adjusted using a potentiometer within the range of 300 to 6000 μT.
  • High-sensitivity sensor that can detect targets from a long distance.
  • Highly stable operation even when the ambient temperature varies thanks to its magnetism focusing construction (Patented).
  • The magnetism focusing construction is very useful as the sensor can detect at a long distance targets with a wide surface but a weak magnetic flux, like belt-shaped rubber magnets.

International Standards

  • Our products do not have overseas safety regulations such as CE mark, UL standard, EN standard etc.
  • Products is compliant to the RoHS directive.

* Please consult about "change of specification" and "request of specification" of the product.

Usage Precautions

  1. If there are magnetic objects on or around the installation location of the electromagnetic sensor, keep a distance between the sensor and these objects greater than the distance between the sensor and the magnet tape.
    Check also carefully the detection characteristics before using the sensor.
  2. If there is magnetic metal with residual magnetism in the surroundings of the electromagnetic sensor installation location,
    the detection characteristics may greatly vary. Verify the detection characteristics before using the sensor.
  3. See Electromagnetic sensor general usage precautions for other precautions.


Precautions with Detection Area Diagram and Reverse Polarity Flux

Precautions with Detection Area Diagram and Reverse Polarity Flux (Typical Example)

When used for bipolar detection, separate sufficiently the sensor from the tape to avoid detecting the reverse polarity magnetic flux output from both sides of the magnet tape.


*If the MGP-EW301 is used at a height of 25 m or less, the wrong pole may be detected.
